Abstract Details

Purpose:

To evaluate the capsulotomy shape changes and the appearance of posterior capsule opacification (PCO) during a 18-months period for bimanual femtosecond laser-assisted cataract surgery (FLACS) in comparison to standard bimanual technique (B-MICS).

Setting:

Institute of Ophthalmology of the University of Modena and Reggio Emilia (Modena, Italy)

Methods:

60 eyes operated by a well-trained surgeon with bimanual FLACS using Ziemer LDV Z8 were included. 60 eyes which underwent standard B-MICS by the same surgeon, served as control group. In all patients a 5.2 mm capsulotomy or capsulorhexis was performed; a Bunny IOL was implanted in the bag. A digital picture of the capsule at slit-lamp was performed at 18-months follow-up visit. Image analysis software (ImageJ) was used to evaluate the diameter and the area of the capsulotomy. PCO score was evaluated using EPCO 2000 software. BCVA and endothelial cell count (ECC) were evaluated at 1,3 and 18 months

Results:

Mean capsulotomy diameter at 18 months in the FLACS group was 5.38±0.09mm, the deviation from baseline of 1.49±0.48 mm2, in the B-MICS group the mean capsulorhexis diameter was 5.45±0.11mm while the deviation area from baseline was 1.85±0.61 mm2 (p>.05). EPCO score was 0.023±0.096 in the FLACS group while 0.067±0.138 in the B-MICS group with statistically significant difference (p<.05). The mean BCVA improvement was significant in both groups. We noticed a statistically significant endothelial cell loss at month 1 and 3 which remained stable through the 18-months follow-up in both groups

Conclusions:

Bimanual FLACS is a safe and effective technique, as determined in a long-term follow-up. Capsulotomy shape in both FLACS and B-MICS groups shows similar variability over 18 months observation period. Femtosecond laser cataract surgery results in lower PCO scores at 18 months in comparison to B-MICS standard technique
